DEGIMA
Also known as DEstination for GPU Intensive MAchine
Operated by Nagasaki University at Nagasaki Advanced Computing Center .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | - NVIDIA GeForce GTX295 cards, 576 GT200 GPUs in total | NVIDIA | 576 reported | Reported | cse.wustl.eduen.wikipedia.org |
| CPU | - Intel Core i7 920 2.66GHz, one per node, 144 nodes | Intel | 144 reported | Reported | cse.wustl.eduen.wikipedia.org |
| Interconnect | - Mellanox MHES14-XTC InfiniBand SDR host adapters, 10 Gbps | Mellanox NVDANASDAQ

The read
GPU cluster at the Nagasaki Advanced Computing Center, Nagasaki University, built for astrophysical N-body simulation. The SC10 paper by Hamada and colleagues describes 144 PC nodes, each with a 2.66GHz Core i7 920, 12GB of DDR3, two GeForce GTX295 cards (four GT200 GPUs per node, 576 in total) and Mellanox InfiniBand SDR, with 24 nodes per 36-port switch, and reports 190.5 TFlop/s sustained on a 3.3-billion-particle treecode run at a hardware cost of about 411,921 US dollars. Wikipedia repeats the 144-node, 576-GPU configuration and explains the name as Destination for GPU Intensive MAchine. No Linpack figure is recorded because none is stated in the sources.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
